This paper describes a measuring system using a laser interferometer in order to calibrate accelerometers absolutely in a low frequency range. This system was developed by the aids of a computer with the following matters; (1) the improvement of voltage measurement involving large waveform distortion, (2) the decrease of a waveform distortion of a vibration exciter, (3) the sensitivity calibration of accelerometers in an arbitrary frequency. The accuracy is estimated to be 0.4% at 0.5 Hz, 0.3% at 1 Hz, 0.2% at 2 to 8 Hz by the calibration of a servo accelerometer.
